He has appeared in one game, last Tuesday, as a pinch-runner.
The Phillies still believe Brown is their left fielder of the future, but if that is the case, why hasn't he played?
"Right now we need other guys to play," Phillies general manager Ruben Amaro Jr. "Right now he's not a guy that we're going to consider for the postseason roster, at least at the outset."
Amaro said he believes Brown has benefited from his time in the big leagues.
"It's a good time for him to be here," Amaro said. "I think it was a good learning tool for him last year. It was a good learning tool for him this year. He needs to know he's a very important part of our organization still, and part of our future."
